2019 Santa Fe has a feature to restart after start-stop at lights, line ques and stop signs. Dealer said it was a faulty battery. He disabled feature for safety but still have rapid battery failure. Need 3rd battery in 3 yrs and 34k miles. Does anyone have insight on this issue. 🤔

Sorry, I don't have any experience with rapid battery failure, but I would LOVE to know how to disable that "feature". I know some have jammed a toothpick into the button to do so, and there is a small 3rd party electronic board you can install to remember the last setting. If there was a setting or switch that could be flipped to do so, that would be so much better/cleaner. Any idea how he disabled it?
